The Great British Dig: History in Your Garden S03E01 - A Lost Tudor Hall in Odiham

Hugh Dennis and the team are in Odiham, Hampshire, searching for the house of Sir Frances Walsingham, the head of Elizabeth I's Secret Service. It is the first time the site has ever been dug, so with very little to go on, our team want to locate the house, work out its size and scale, and what Walsingham may have used it for. As part of the investigation, Hugh turns his hand to spy craft as he learns how Walsingham used to break codes.
